PATTERN OF RHEUMATIC DISEASES IN THE DIVISION OF RHEUMATOLOGY, DR. SOETOMO GENERAL ACADEMIC HOSPITAL, SURABAYA, INDONESIA, BETWEEN NOVEMBER 2021 AND MARCH 2022

Highlights: Rheumatic diseases, like many others, are often misdiagnosed and treated late in life, resulting in the increase of rheumatic diseases incidence. Gender, age, level of education, and occupation all play crucial roles in the onset of rheumatic disorders. Abstract Background: The epidemiology of rheumatic diseases plays an important role in the spread of rheumatic diseases worldwide. Epidemiology data of rheumatology diseases in Dr. Soetomo General Academic Hospital remains unclear as there are some problems such as rheumatic drug depletion and imperfect medical recording. Objective: This study aimed to analyze the pattern of rheumatic diseases at the Division of Rheumatology, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. Material and Method: This prospective descriptive study used secondary data from medical records between November 2021 and March 2022 at the Division of Rheumatology, Dr. Soetomo General Academic Hospital. The variables of this study were gender, age, occupation, education level, disease duration, and clinical manifestations. Results: Secondary data was provided by 109 patients in this study. Gender was dominated by women as much as 96 (88%), age was dominated by age groups 26-35 years and 46-55 years, each as much as 26 (23.8%), educational level was dominated by senior high school as much as 24 (22%), and employment was dominated by housewives as much as 39 (35.7%) in the Divison of Rheumatology, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. Based on disease incidence, 42 patients (38.5%) had systemic lupus erythematosus, and 38 patients (34.8%) had ankylosing spondylitis. Conclusion: Rheumatology patients at Dr. Soetomo General Academic Hospital Surabaya are predominantly female, aged 26-55, with senior high school education. The diseases mostly affect housewives and have a higher frequency of systemic lupus erythematosus and ankylosing spondylitis.

TTP: long-term outcomes following recovery.

Although risk for relapse may be the greatest concern following recovery from acquired, autoimmune thrombotic thrombocytopenic purpura (TTP), there are multiple other major health issues that must be recognized and appropriately addressed. Depression may be the most common disorder following recovery from TTP and may be the most important issue for the patient's quality of life. Severe or moderate depression has occurred in 44% of Oklahoma Registry patients. Recognition of depression by routine screening evaluations is essential; treatment of depression is effective. Minor cognitive impairment is also common. The recognition that cognitive impairment is related to the preceding TTP can provide substantial emotional support for both the patient and her family. Because TTP commonly occurs in young black women, the frequency of systemic lupus erythematosus, as well as other autoimmune disorders, is increased. Because there is a recognized association of TTP with pregnancy, there is always concern for subsequent pregnancies. In the Oklahoma Registry experience, relapse has occurred in only 2 of 22 pregnancies (2 of 13 women). The frequency of new-onset hypertension is increased. The most striking evidence for the impact of morbidities following recovery from TTP is decreased survival. Among the 77 patients who survived their initial episode of TTP (1995-2017), 16 (21%) have subsequently died, all before their expected age of death (median difference, 22 years; range 4-55 years). The conclusion from these observations is clear. Following recovery from TTP, multiple health problems occur and survival is shortened. Therefore, careful continuing follow-up is essential.

Progressive multifocal leukoencephalopathy: A national estimate of frequency in systemic lupus erythematosus and other rheumatic diseases

Progressive multifocal leukoencephalopathy (PML) is a rare, typically fatal, central nervous system demyelinating disease that results from reactivation of the JC virus, which generally occurs in immunosuppressed hosts. The aim of this study was to generate a national estimate of the frequency of PML among patients with rheumatic diseases. Data were obtained from the Nationwide Inpatient Sample database. This is a 20% sample of all hospital discharges, weighted to represent the entire US inpatient population. Data were analyzed for the years 1998-2005 inclusive, representing 297,797,180 hospital discharges. Cases of PML, systemic lupus erythematosus (SLE), and other rheumatic diseases were identified by diagnostic codes from the International Classification of Diseases, Ninth Revision, Clinical Modification. A total of 9,675 cases of PML were identified. The majority were associated with human immunodeficiency virus (HIV; 7,934 patients [82.00%]), hematologic cancers (813 patients [8.40%]), and solid cancers (274 patients [2.83%]). Among the rheumatic diseases, 43 cases of PML (0.44%) were associated with SLE, 24 (0.25%) with rheumatoid arthritis (RA), and 25 (0.26%) with other connective tissue diseases (CTDs). When patients with other potential risk factors for PML (HIV, malignancy, bone marrow or other organ transplantation) were excluded, the rates of PML per 100,000 discharges coded for SLE, RA, and other CTDs were 4, 0.4 and 2, respectively, compared with a rate of PML in the background population of 0.2/100,000 discharges. This study was confined to hospitalized patients with rheumatic diseases, and it was also limited by the lack of information regarding immunosuppressive therapy. Nevertheless, the findings suggest that, although rare overall, PML occurs more commonly in SLE than in other rheumatic diseases.

Complement activation as a mediator of antiphospholipid antibody induced pregnancy loss and thrombosis

The antiphospholipid antibody syndrome (APS) is characterised by increased risk of vascular thrombosis involving venous, arterial, and placental circulations. The last of these is associated with poor obstetrical outcomes, including...

INHERITED DEFICIENCIES OF COMPLEMENT IN RHEUMATIC DISEASES

Inherited complement deficiencies are rare but occur with increased frequency in systemic lupus erythematosus. This selective review summarizes the fundamentals of complement activation and biology and focuses on recent findings. system lupus erythematosus is highly associated with homozygous C1q deficiencies and with C4A null allotypes, and homozygous C2 and C3 deficiencies are less uniformly associated with autoimmune disease. This hierarchy of disease associations suggests the importance of an intact early classic activation pathway in preventing systemic lupus erythematosus. Assays of complement activation products may have greater sensitivity and specificity for systemic lupus erythematosus disease activity and lupus flares.

Clinical, serologic, and immunogenetic studies in childhood‐onset systemic lupus erythematosus

To determine the frequency of systemic lupus erythematosus (SLE)-associated clinical manifestations, autoantibodies, and HLA class II alleles in a large cohort of patients with childhood-onset SLE. Eighty children with SLE onset before age 18 (27 before age 11) were studied for the frequency of renal, neuropsychiatric, and hematologic complications as well as for anti-native DNA, Ro, La, Sm, and U1 RNP autoantibodies. HLA-DR, DQ, and DP alleles were determined by oligotyping. The results were compared with findings in 213 adults with SLE onset at or after age 18 years. Renal involvement was more frequent in those with childhood-onset SLE, especially those with onset before age 11 (82%, compared with 53% in adults). Anti-U1 RNP was more common in American blacks with SLE onset before age 18. HLA-DRB1*0301, DQA1*0501, DQB1*0201 was more common in Caucasians and DRB1*1503, DRB5*0101, DQA1*0102, DQB1*0602 in American blacks, regardless of age at SLE onset. Anti-Sm autoantibodies were most highly associated with HLA-DQA1*0102 and DQB1*0602. While childhood-onset SLE shares many immunogenetic and serologic similarities to adult-onset disease, important clinical differences nevertheless exist in children with this disease.

Frequency of systemic lupus erythematosus in different ethnic groups in hawaii

A survey of systemic lupus erythematosus (SLE) patients was conducted in civilian general hospitals on Oahu, Hawaii for the years 1970-75. One hundred sixty-eight cases were ascertained, of which 107 were considered "definite." Age-adjusted prevalence rates per 100,000 were estimated for definite cases at the end of 1975 as follows: white 5.8, Chinese 24.1, Filipino 19.9, part-Hawaiian 20.4, and Japanese 18.2. There was a heavy preponderance of females in each ethnic group, averaging 90% of the definite cases overall. Review of vital statistics for the United States and Hawaii during this period showed age-adjusted SLE mortality rates per million as follows: U.S. white 3.04, U.S. non-white 8.82, Hawaii white 1.89, Hawaii non-white 14.46. The cause of the very high SLE prevalence and mortality in the Oriental and Polynesian people of Hawaii is not clear.

B-Lymphocyte Alloantigens Associated with Systemic Lupus Erythematosus

We examined B-lymphocyte alloantigens in 41 patients with systemic lupus erythematosus and 184 controls, using a panel of 47 pregnancy serums, and compared reaction frequencies of individual serums. One serum, la-715, reacted with B lymphocytes from 75.6 per cent of patients and 14.1 per cent of controls (Pc less than 0.005, relative risk 18.8). Twenty-eight of the patients were also typed with a panel of HLA-D-related serums from the Seventh International Histocompatibility Workshop, HLA-DRw types assigned, and compared to 490 Workshop controls. Both HLA-DRw2 (57.1 per cent vs. 26.4 per cent, Pc less than 0.004) and HLA-DRw3 (46.4 per cent vs. 22.2 per cent, Pc less than 0.03) were increased in systemic lupus erythematosus. This study demonstrates that select B-lymphocyte alloantigens, which are controlled by genes in the major histocompatibility complex, are present in increased frequency in systemic lupus erythematosus.
