Fatal primary dengue-induced Haemophagocytic Lymphohistiocytosis (HLH) in a returning traveller from India treated with anakinra for the first time

Abstract Background Dengue fever is an arthropod-borne flavivirus infection that is highly prevalent in the tropics. A proportion of clinical cases develop severe dengue, defined by life-threatening complications including haemorrhage, capillary leak and multi-organ failure. Recently there has been increasing recognition that some cases of severe dengue may be a consequence of HLH. To our knowledge, this is the first report of treatment with Anakinra for dengue-induced HLH. Case report We report a case of Dengue fever triggering HLH in an eighteen-year-old female returning traveller from India, diagnosed with systemic lupus erythematosus (SLE) two months prior to presentation. The patient initially presented to a district general hospital emergency department (ED) with a three-day history of flu-like symptoms, fever, erythematous rash, widespread joint pain, nausea and chills. Acute Dengue virus infection was confirmed with serum polymerase chain reaction (PCR) testing. On day two, she was admitted to intensive care for multi-organ support necessitated by refractory hypotension, oligo-anuric severe acute kidney injury (AKI), acute liver failure with lactataemia and type one respiratory failure. The possibility of Dengue-induced HLH was considered early with multiple criteria for diagnosis met including hyperferritinaemia, pancytopenia, lipaemia and a marked transaminitis. HLH-directed therapy was commenced with intravenous immunoglobulins (IVIG), intravenous methylprednisolone (IVMP) and Anakinra. Subsequent bone marrow biopsy analysis demonstrated clear evidence of HLH, in the context of a persistent and marked Dengue viraemia. We observed resolution of HLH markers as well as reducing requirements for multi-organ support after initiation of Anakinra therapy. During her recovery, the patient unexpectedly developed focal neurology; intracranial imaging demonstrated widespread, discreet parenchymal lesions thought to be haemorrhagic in nature, which were deemed too severe an insult to recover from. On day 19, the difficult decision of withdrawing care after deep discussion with the family was reached, soon after which the patient passed away. A post-mortem examination was not arranged.

Lack of evidence that beta blocker use reduces knee pain, areas of joint pain, or analgesic use among individuals with symptomatic knee osteoarthritis

The potential for beta blocker use to reduce joint pain and analgesic use in osteoarthritis (OA) patients has not been well established. The objective of this study was to estimate the association between beta blocker use and knee pain, areas of joint pain, and analgesic use among participants with symptomatic knee OA. We selected participants with symptomatic knee OA from the Osteoarthritis Initiative. Outcome measures included knee pain (e.g., WOMAC pain subscale), areas of joint pain (e.g., widespread joint pain), and analgesic use (e.g., use of strong pain prescriptions including opioids). We decomposed time-varying beta blocker use into within-person and between-person variation, and included these components in linear mixed effects models for repeated outcome measures of knee pain, joint pain, and analgesic use over 8 years. Among 1,168 participants, 15% reported beta blocker use at baseline. Beta blocker users (5.2, 95% CI [4.7, 5.8]) had similar estimated mean WOMAC pain scores as other anti-hypertensive users (4.9, 95% CI [4.6, 5.2]), with an estimated within-person difference of 0.1 (95% CI [-0.3, 0.4]). Proportion of participants reporting widespread joint pain was similar between beta blocker users and other anti-hypertensive users (40.1% vs 40.3%; within-person effect, odds ratio [OR]=0.87, 95% CI [0.63, 1.22]). Reported use of strong prescription pain medication was also similar between beta blocker users and other anti-hypertensive users (7.7% vs 8.2%; within-person effect, OR=1.39, 95% CI [0.75, 2.55]). We found no evidence that beta blockers confer a clinically meaningful reduction in knee pain severity, areas of joint pain, or analgesic use among participants with symptomatic knee OA.

Hepatitis C, an unusual cause of inflammatory arthritis: a case report

A 51-year-old gentleman of Pakistani origin, living in the UK for the last 20 years, presented to the rheumatology department with a 10-year history of widespread joint pain and deformity. He had a background of idiopathic thrombocytopaenic purpura (ITP), chronic folliculitis, osteoporosis and

Ochronosis in differential diagnosis of patients with chronic backache: a review of the literature

A 50-year-old man presented with a complaint of low-back pain and widespread joint pain for the previous 20 years. Conventional radiography revealed wide areas of calcification in the intervertebral discs and degenerative changes in the peripheral joints. A diagnosis of ochronosis was made by the observation of bluish-brown pigmentation in the nose and ears, dark urine colors following alkalization, and high levels of homogentisic acid in the urine. Ochronosis should be considered in the differential diagnosis of patients with chronic low-back pain regarding features of widespread calcification in the intervertebral discs at radiography and bluish-brown pigmentation in the nose and ears.

Osteomalacia from Mg-containing antacid: a case report of bilateral hip fracture

Non-prescribed antacid drugs that contain magnesium and aluminum are widely used in the treatment of gastritis and peptic ulcer. One of the side effects of these antacid drugs is that they bind phosphate in the gut and result in its malabsorption. In this paper, a 42-year-old female patient who used magnesium hydroxide (Magnesie calcinee powder 100 g) to benefit from its laxative feature, and developed osteomalacia after losing 90 kg in 2 years will be presented by going through the related literature. She had widespread joint pain and could hardly walk without the help. Ca, P and vitamin D were at lower limit of normal, ALP, Mg and PTH were increased in her laboratory tests. There were stress fractures at the femur neck and at the upper part of the tibia in plane radiographies. The patient was hospitalized with the diagnosis of osteomalacia and she was treated successfully.
